Argyle Australian Champagne Diamond — 0.51 ct Oval | C5 - Med Champagne
Why we chose this stone
Just past the half carat mark, this oval cut champagne diamond carries the rich amber-gold colour of the C5 Medium Champagne grade with quiet confidence. It's a shade prized for sitting right at the midpoint of the champagne spectrum — deep enough to be unmistakably coloured, yet bright enough to retain the lively sparkle diamonds are known for. This stone's origins trace to Western Australia's now-closed Kimberley mine, historically responsible for the vast majority of the world's naturally occurring champagne diamonds.
At 0.51ct, this oval offers meaningful size for a solitaire or feature stone, with the elongated cut drawing the eye along its length and showcasing the colour evenly from tip to tip. Diamonds of this weight and grade are well suited to those wanting a coloured diamond that still reads as a serious, substantial piece. Selected for its saturation and cut symmetry, this stone represents genuine Australian diamond heritage in a versatile, wearable size.

I’ve purchased several diamonds and a range of other stones including opals, sapphires and more from Julie. The quality and price point was excellent. Her calm, relaxed approach to creating bespoke jewellery has been spot on every time. I wouldn’t go anywhere else.

The experience I had throughout this process was amazing. Not knowing much about this area, Julie took the time to explain everything to me in detail, which gave me a lot of comfort.I could not fault the price, the quality and experience I had with Hope Diamonds. A very very successful journey with Julie and the team :) I highly recommend Hope Diamonds.
